Calcite, alpha-BBO, undoped YVO4, quartz and MgF2 crystal are the most common birefringent crystals.

Alpha-BBO is transparent in deep UV range, and YVO4 has the high transmittance in the middle IR range.

Alpha-BBO, Calcite and undoped YVO4 have the big birefringence, which are suitable for polarizing prisms. The birefringence of Quartz and MgF2 is relatively small, which makes them the best materials for wave plates.
